SUMMARY

The Breit-Wigner profile is utilized to describe gamma ray emissions due to its mathematical properties as the Fourier transform of the exponential decay function associated with nuclear decay. This profile effectively represents the energy distribution of emitted gamma rays, where the x-axis denotes energy and the y-axis indicates intensity. Understanding this relationship is crucial for interpreting nuclear decay processes and gamma ray spectra accurately.

PREREQUISITES
  • Basic understanding of nuclear decay and exponential functions
  • Familiarity with Fourier transforms in mathematical physics
  • Knowledge of gamma ray emissions and their characteristics

Hello PF members,
I curious to know some basic idea..why the line shape of nuclear decay is displayed as a Breit-Wigner (BW) profile (x-axis as energy and y-axis as intensity) ??.. or any \gamma ray is often shown as a BW profile??

thanks for your reply.

Because the Breit-Wigner is the Fourier transform of the exponential. Does this answer your question?
 
Well..i hope your answer should be completely correct!
I actually know that nuclear decay is a sort of exp. function...but when i was thinking of my question...i dint get the idea of FT.
thanks
